iterative reconstruction techniques meaning in Chinese

迭接重建技术

We performed crosswell tomography on a real crosswell seismic line from shengli oilfield by using simultaneous iterative reconstruction technique ( sirt ) based on shortest path tree ( spt ) curved ray tracing
摘要利用基于最短路径树弯曲射线追踪的联合迭代重建层析成像( sirt )技术进行井间地震层析成像，对胜利油田的一对井间实际资料进行了处理。
The authors established an initial velocity model based on the first break time of the actual data , then realized the forward calculation with the improved shortest path ray tracing algorithm , and applied the improved constrained damped simultaneous iterative reconstruction technique ( cdsirt ) to solve large - scale and sparse equations for inversing the near - surface velocity field
根据实际地震数据的初至波时间建立初始速度模型；采用改进的最短路径射线追踪算法进行正演；利用改进的约束带阻尼联合迭代重建技术( cdsirt )求解大型、稀疏的方程组来反演近地表的速度场。
